THOMAS BARBER, OF FLATBUSH, NEW YORK.

PULLEY-BLOCK HOOK.

$PECIFICATION forming part of Letters Patent No. 364,079, dated May 31, 1887.

Application filed February 3, 1887. Serial No. 226,432. (No model.)

To all whom it may concern.-

7 Be it known that I, THOMAS BARBER, a citizen of the United States, residing at Flathnsh, in the county of Kings and State of New York, have invented new and useful Improvements in Pulley-Block Hooks, of which the following is a specification.

This invention relates to an improvement in pulley-blocks, as set forth in the following specification and claims, and illustrated in the accompanying drawings, in which:-

Figure 1 is a front elevation of a pulleyblock. Fig. 2 is a detail view of a lifting- Fig. 3 is a section'in the plane 00 m, Fig. 2.

Similar letters indicate corresponding parts.

In Fig; l the pulley-block is shown as being connected by a hook, A, to a suitable support, B. The operatingwheel Oof the block transmits motion to the transmitting or lifting wheels D in any well-kn0wn way. The motion of the lifting-wheels D is' communicated to the lifting-chain E. Any object connected to the lifting-chain E can be raised or lowered by actuating the operating-wheel C.

To connect any object to the lifting-chain E, a hook, F, is provided. The hook F is provided with a slotted arm or support, G. The

slots I of the arm G, as seen in Fig. 2, are.

adapted to sit over links of the lifting-chain E, so that the hook F will move with the lifting-chain. The support or arm G can thus be readily connected to or disconnected from the chain E. In order to connect the lifting chain to any object, it is not necessary to bring any specific part of the lifting-chain near to the object, because the hook F can be connected to the object, and the slots I of the arm G can be brought into engagement with any portion of the lifting-chain E that is conveniently near to the slots I. To disengage the hook F from the liftingchain, thelifting-chain is slipped out of the slots I. By connecting the hook F to the arm G at or near the for-' or the hook and arm may be connected by a swivel-connection, H.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with alifting-chain, E, of a hook, F, provided with a slotted arm or support adapted to engage the 1ifting-chain, substantially as set forth.

2. The combination, with a lifting-chain,- E, of a hook, F, provided with a slotted arm or support adapted to engage the lifting-chain,

said hook F being connected to the arm or support near the forward or open end of the slot in said arm or support, substantially as set forth.

3. The combination, with a lifting-chain, E,- a hook, F, and a slotted arm or support adapted to engage thelifting-chain, of a swivelconnection adapted to unite the hook and the arm or support, substantially as set forth.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
